Temperature measurement principle
The principle of infrared thermometer's temperature measurement is
to convert the radiant energy possessed by
infrared rays emitted by the measured object into electrical
signals. The amount of infrared radiation energy is
related to the temperature of the object itself, and the
temperature of the object can be determined according to
the size of the converted electrical signal. All objects above
absolute zero will radiate infrared rays by
themselves. The function of the infrared thermometer is to collect
the infrared rays emitted by the object. It will
not emit any harmful radiation at all, so it is completely harmless
to the human body. Some people have
misunderstood that infrared thermometers emit radiation to the
human body to produce readings. This concept is
wrong.
